Hall effect sensor with ASIL A certification ALLEGRO APS12626LLHALX-BAP featuring quadrature outputs
Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for ring magnet applications. They feature orthogonal vertical and planar Hall elements, providing 90 phase separation independent of magnet pole spacing and air gap, eliminating the need for target optimization. These devices offer flexibility in orientation with XY, ZX, and ZY options. The APS12625 provides Speed and Direction outputs, while the APS12626 offers quadrature outputs (Channel A/B). A unique power-cycling restore feature (-P option) prevents lost counts/pulses. They are ISO 26262:2011 / ASIL A compliant, operate from 2.8 to 5.5 V, and are automotive grade qualified per AEC-Q100 up to 175C TJ.
